A lock for a household appliance, such as a tumble drier, a washing machine, a dishwasher or the like, has a movable retaining element. The movable retaining element is configured in the style of a slider for interaction with a locking bar located on a door, a lid, a hinged opening or the like of the household appliance. The lock has a two-state locking mechanism for the retaining element, such that the locking mechanism in a first state blocks the movement of the retaining element and in a second state frees the movement of the retaining element. The locking mechanism can be electromagnetically controlled between the two states.

Lock for a household appliance

A sensor for detecting a rupture or length change in a belt. The sensor has a movable transmission element operatively connected to the belt, that acts on an electrical switch having a contact system in the event of a length change or rupture of the belt. The contact system comprises a switching contact with a contact surface arranged on a first end, and an associated fixed contact. The transmission element acts on the second end of the leaf spring. A limb extends approximately from the first end of the leaf spring in the direction of the second end, and a further limb extends from the second end of the leaf spring in the direction of the first end. The free ends of the two limbs are clamped offset from one another on a carrier part of the switch, such that the switching contact switches over in a bistable manner.
